. The main objects of this invention are to provide an improved barsupport and spacer for use in reenforcing systems of concreteconstruction work; and to provide an improved high-chair for reenforcingbars wherein sections of identical construction are secured together toform the complete support and spacer, thereby reducing its cost andfacilitating its manufacture and assem- 10 bly.

An illustrative embodiment of this invention is shown in theaccompanying drawings, wherein:

chair.

The common types of bar supports and spacers heretofore in use generallyincluded two or more separately formed members of different shapes whichwere welded 01, otherwise secured together. It was, therefore, necessaryfor the manufacturer to carry in stock a large supply of each part ofthe units.

In the construction herein shown, the improved high-chair comprises twosections of substantially identical size and shape which are rigidlysecured together to form the com- I chair comprises a pair ofsubstantially identical sections 3, which are rigidly secured together.

Each of the sections 3 comprises a wire which is bent to form ahorizontal shelf l,

Fig. 3 is a top plan of an improved highand an upstanding arm-5, havingtheir outer ends bent downwardly to .form depending legs 6 and 7,respectively. The shelf el, arm 5 and leg 7 of each section arepreferably located in a single plane, from which the leg 6 divergesdownwardly.

When the sections areassembled, they are arranged as shown in Fig. 1,with the shelves :1, arms 5 and legs 7 of bothsections located insubstantially a single vertical plane and ,the legs 6 divergingdownwardly on respectively opposite sides of that plane. The shelves 1are preferably spot welded together, as shown at 8, and together withthe arms-5 they form a substantially U-shaped saddle for supporting ther'eenforcing bar. The legs 7 of the assembled. unit preferably divergedownwardly from each other.

The high-chairs embodying these improvements are exceedingly simpleinconstruction and operation, comparatively inexpen-o s'ive tomanufacture, and up.

I claim:

1. A bar support comprising a substantially U-shap-ed wire saddle havinga horizontal base part and a pair of upstanding arms, the upper ends ofsaid arms being bent downwardly to provide a' pair of end legs, and apair of intermediate legs on respectively opposite ends of said basepart, said intermediate legs diverging downwardvery rigid when set 1y onrespectively opposite sides of the plane of said saddle.

2. A bar support comprising a substantially U-shaped wire saddle havinga horizontal base part and a pair of upstanding arms, the upper ends ofsaid arms being bent downwardly to provide a pair of end legs, said endlegs and saddle being disposed in substantially a single plane, and apair of intermediate legs on respectively oppoe site ends of said basepart, said intermediate legs diverging downwardly on respectivelyopposite sides of the plane of said saddle.

3. A. bar support comprising a substantially U-shaped wire saddle havinga horizontal base part and a pair of upstanding arms, the upper ends ofsaid arms being bent downwardly to provide a pair of end legs, said endlegs diverging downwardly from each other within the plane of saidsaddle, and a pair of intermediate legs on respectively opposite ends ofsaid base part, said intermediate legs being located on respectivelyopposite sides of the plane of said saddle and diverging downwardlytherefrom.

4. A bar support comprising apair of connected wire sections ofsubstantially identical construction, each of said sections comprisingan L-shaped portion having both of its ends bent downwardly to provide apair of depending legs the L-shaped portions of both sections beingunited to form a U-shaped saddle for supporting a reenforcing bar.

5. A bar support comprising a pair of connected wire sections ofsubstantially identical construction, each of said sections comprisingan L-shaped portion having both of its ends bent downwardly to provide apair of depending legs, the L-shaped portions of both sections beingunited at their bases to form a U-shaped saddle for supporting areen'forcing bar one leg of each section being disposed in the plane ofsaid saddle, the other leg of each section diverging downwardly fromsaid plane.
